@gwen-dragon I did that and there was a thing from McAfee that wasn't active. I deleted it and closed Vivaldi. When I reopened Vivaldi the site still didn't work. This site works on SeaMonkey & Iron. Then I went to my laptop (Win 10 64 also) Vivaldi won't load the lines there either but Pale Moon will. I appreciate the help and I would understand if you wanted to give up here.

@bakerbob I don't use 3rd party virus protection anymore. Can Windows virus & Firewall cause these types of symptoms?
I'm just spitballing here, based on what the 2 machines have in common. At the end of the day it's probably going to be a problem with the operator :)
